In an experiment to determine its composition, an aspirin tablet was crushed and dissolved in water. Acetylsalicylic acid (C9H8O4) is amonoprotic acid commonly known as "aspirin." A typical aspirin tablet, however, contains only a small amount of the acid. It took 11.75 mL of 0.1466 M NaOH to neutralize the solution. Determine the number of grains of aspirin in the tablet.
